2. The abnormality alarm device (10) according to claim 1, wherein the information regarding the abnormality alarm device (10) includes information regarding an operation history of the abnormality alarm device (10).
3. The abnormality alarm device (10) according to claim 1, wherein the information regarding the abnormality alarm device (10) includes a number of times the operation unit is operated.
4. The abnormality alarm device (10) according to any one of claims 1 to 3, wherein the information regarding the abnormality alarm device (10) includes an accumulated operation time of the abnormality alarm device (10).
5. The abnormality alarm device (10) according to any one of claims 1 to 4, wherein the information regarding the abnormality alarm device (10) includes an accumulated number of times the report unit (13) has reported the occurrence of the abnormality.
6. The abnormality alarm device (10) according to any one of claims 1 to 5, wherein the information regarding the abnormality alarm device (10) includes an accumulated number of times the report unit (13) has reported the occurrence of the abnormality in a predetermined period.
7. The abnormality alarm device (10) according to any one of claims 1 to 6, wherein the sensor (11) is a smoke detection sensor (11) of an optical type, and the information regarding the abnormality alarm device (10) includes information indicating a degree of dirtiness of the smoke detection sensor.

Description

TECHNICAL FIELD The present invention relates to an abnormality alarm device. BACKGROUND ART Conventionally disclosed is a system which notifies information regarding an abnormality alarm device (for example, abnormality (failure) of a fire alarm device) to an external information terminal such as a smartphone or a tablet via a gateway (for example, JP 2012-181814 A). Consequently, a user can check the aforementioned information on the information terminal. EP 2 264 681 A1 discloses an alarm device including: a wireless circuit section which wirelessly exchanges event signals with an other alarm device; an alert section which outputs an alarm; an operation section which accepts predetermined operations; a sensor section which issues an abnormal condition detection signal when an abnormal condition occurred is detected within a monitoring area; an abnormal condition monitoring section which, upon receiving the abnormal condition detection signal from the sensor section, outputs an abnormal condition alarm as a linkage source from the alert section, and transmits an event signal indicating an abnormal condition to the other alarm devices, and conversely, upon receiving an event signal indicating an abnormal condition from the other alarm device, outputs an abnormal condition alarm as a linkage destination from the alert section; a communication test transmission processing section which, at a predetermined timing, transmits an event signal indicating a communication test to the other alarm device and; a communication test reception processing section which, upon receiving an event signal indicating a communication test from the other alarm device, announces the reception status of this event signal. DE 20 2014 002931 U1 shows a light-emitting semiconductor projection unit projecting the user-side information having alphanumeric character, danger symbol, evacuation symbol and service icon, such that the additional information and alarm or servicing information can be provided visually, quickly and easily. JP 2006 099263 shows an alert apparatus for alerting gas leakage, outputs light alert signal to LEDs based on gas leakage detection result, and superimposing preset gas leakage data on alert signal. An external device extracts and displays the superimposed data on display. SUMMARY OF INVENTION PROBLEM TO BE SOLVED However, it is required to provide the system disclosed in JP 2012-181814 A with a gateway separately from an abnormality alarm device. Thus, it takes labor and cost to form such a system, which brings about a problem that the system can be hardly brought into general households. Thus, it is an object of the present invention to provide an abnormality alarm device capable of outputting information regarding the abnormality alarm device to an information terminal without using a gateway. SOLUTION TO PROBLEM An abnormality alarm device according to the present invention is defined in independent claim 1. Preferred embodiments are defined in dependent claims 2 to 7. ADVANTAGEOUS EFFECT OF INVENTION An abnormality alarm device according to one aspect of the present invention makes it possible to output information regarding an abnormality alarm device to an information terminal without using a gateway. BRIEF DESCRIPTION OF DRAWINGS FIG. 1 is a configuration diagram illustrating one example of an abnormality alarm device according to an embodiment.FIG. 2 is an outer perspective view illustrating one example of the abnormality alarm device according to the embodiment.FIG. 3 is a diagram illustrating one example of a conventional abnormality alarm system. DESCRIPTION OF EXEMPLARY EMBODIMENT Knowledge as Basis of Present Invention First, the knowledge as a basis of the present invention will be described with reference to FIG. 3. FIG. 3 is a diagram illustrating one example of a conventional abnormality alarm system. Abnormality alarm device 10a is a fire alarm device which is installed in a housing, an office, or a facility such as a commercial facility, detects, for example, smoke or heat in fire as an abnormality, and reports by sound or the like that the abnormality has occurred. Moreover, abnormality alarm device 10a includes, for example, an operation unit (buttons, etc.) operated by a user, and checks a self-state (for example, an abnormality (failure or the like) of abnormality alarm device 10a) as a result of operation performed on the operation unit. For example, there have been demands for checking, from information terminal 100 such as a smartphone or a tablet, information such as results of the aforementioned check and information regarding another abnormality alarm device 10a. Information terminal 100 needs to receive the aforementioned information via, for example, a wireless network, which therefore requires gateway 200. Gateway 200 is a device which has a function as a network node for connecting together networks with mutually different protocols like, for example, a wired network connecta
